Optical fiber ntau transceiver yog Ethernet kis tau tus mob media conversion unit uas sib pauv luv luv twisted khub hluav taws xob signals thiab ntev-ntev optical signals.Raws li nws cov kev xav tau, nws tau muab faib ua ib leeg-fiber optical transceivers thiab dual-fiber optical transceivers.Tom ntej no, peb yuav qhia kom meej dab tsi yog ib hom single-fiber/dual-fiber optical transceiver?Dab tsi yog qhov txawv ntawm ib hom ib leeg-fiber thiab ib hom dual-fiber optical transceivers?Yog xav paub ntxiv, cia peb saib!
Dab tsi yog aib hom ib leeg-fiber optical transceiver?
Ib hom ib leeg-fiber optical fiber ntau transceiver, ib leeg-fiber khoom yuav txuag tau ib nrab ntawm optical fiber, uas yog, kom ua tiav cov ntaub ntawv txais thiab kis tau tus mob ntawm ib tug optical fiber.
Ib leeg-fiber optical fiber transceiver: Cov ntaub ntawv tau txais thiab xa mus rau ntawm ib qho fiber ntau optical.Raws li lub npe qhia, cov khoom siv fiber ntau tuaj yeem txuag tau ib nrab ntawm cov khoom siv kho qhov muag, uas yog, tau txais thiab xa cov ntaub ntawv ntawm ib qho khoom siv fiber ntau, uas yog qhov tsim nyog rau qhov chaw uas cov khoom siv fiber ntau nruj.Cov khoom siv no siv wavelength division multiplexing technology, thiab feem ntau ntawm cov wavelengths siv yog 1310nm thiab 1550nm.Txawm li cas los xij, vim tias tsis muaj kev sib koom ua ke thoob ntiaj teb tus qauv rau ib leeg-fiber transceiver cov khoom, cov khoom ntawm cov tuam txhab sib txawv yuav tsis sib haum thaum lawv sib cuam tshuam.Tsis tas li ntawd, vim yog kev siv wavelength division multiplexing, ib leeg-fiber transceiver khoom feem ntau muaj cov yam ntxwv ntawm cov teeb liab loj attenuation.Tam sim no, feem ntau ntawm cov fiber ntau optic transceivers nyob rau hauv kev ua lag luam yog dual-fiber khoom, uas yog ntau paub tab thiab ruaj khov, tab sis yuav tsum tau ntau fibers.
Dab tsi yog aib hom dual-fiber optical transceiver?
Ib hom dual-fiber optical fiber ntau transceiver, thiab ib leeg-fiber bidirectional optical fiber transceiver hom yog photoelectric hloov dua siab tshiab khoom, uas muaj qhov zoo ntawm kev txuag ib nrab ntawm fiber.
Ib leeg-fiber bidirectional optical fiber transceiver yog ib tug photoelectric hloov dua siab tshiab ntaus ntawv uas siv wavelength division multiplexing tshuab xa thiab tau txais cov ntaub ntawv ntawm ib tug optical fiber, thiab converts network hluav taws xob signals thiab kho qhov muag teeb liab.Ib leeg-fiber bidirectional optical fiber transceivers tau dhau los ua neeg nyiam nyob rau xyoo tas los no.Qhov zoo dua yog tias nws tuaj yeem txuag tau ib nrab ntawm cov khoom siv kho qhov muag.Tsis muaj kev sib koom ua ke thoob ntiaj teb tus qauv rau qhov tsis muaj ib nrab ntawm cov khoom siv kho qhov muag.Cov khoom tsim los ntawm ntau lub tuam txhab yog feem ntau sib xws thiab muaj kev ruaj ntseg me ntsis dua li cov khoom siv fiber ntau dual.Tam sim no, fiber ntau optic transceivers ntawm kev ua lag luam tseem yog cov khoom siv fiber ntau dual.
Dab tsi yog qhov txawv ntawmsingle-mode single-fiber thiab single-mode dual-fiber optical transceivers?
Single-hom multi-mode nyob ntawm qhov kho qhov muag cable, ib leeg-fiber dual-fiber hais txog ib-core fiber ntau kis tau tus mob los yog ob-core fiber ntau kis tau tus mob;single-mode hais txog kev siv ib hom kev kho qhov muag cables, ib leeg-fiber transceivers siv ib leeg xwb, ob qho tag nrho ob qho tib si txuas nrog cov tub ntxhais no, thiab cov transceivers ntawm ob qhov kawg siv qhov sib txawv optical wavelengths, yog li optical signals yuav kis tau rau hauv ib core.Lub dual-fiber transceiver siv ob lub cores, ib qho rau xa thiab lwm qhov rau kev txais, ib kawg yog kis thiab lwm qhov kawg yuav tsum tau muab tso rau hauv qhov chaw txais txais, uas yog, ob qhov kawg yuav tsum hla.
Hauv kev thov tshwj xeeb ntawm ib hom thiab dual-hom, tus nqi ntawm ntau hom yog siab dua li ntawm ib hom, feem ntau nyob rau hauv cov kab hluav taws xob hauv qab 500m, ntau hom tuaj yeem ua tau raws li, txawm hais tias qhov kev ua tau zoo tsis zoo. raws li ib hom.Ib hom yog siv nyob rau hauv ib puag ncig siab tshaj 500m los yog nyob rau hauv ib puag ncig uas yuav tsum tau bandwidth siab, feem ntau nyob rau hauv loj-scale daim ntaub ntawv xws li enterprise theem.Vim tias kev ua haujlwm ruaj khov thiab kev ua haujlwm ntawmoptical fiber moduleszoo dua li transceivers, nyob rau hauv ib hom ntawv thov uas yuav tsum tau muaj kev ua tau zoo, ob peb lub tuam txhab siv transceivers, tab sis ncaj qha siv modules xwb.
Ib leeg fiber ntau thiab dual fiber ntau feem ntau muaj ob qhov chaw nres nkoj, thiab ob qhov chaw nres nkoj ntawm dual fiber ntau yog nyob ze.Lawv raug cim nrog TX thiab RX, ib qho rau kev xa thiab ib qho rau kev txais, uas raug xaiv;ob qhov chaw nres nkoj rau ib qho fiber ntau feem ntau yog P1, P2 qhia tias ob qhov chaw nres nkoj tuaj yeem xa thiab tau txais nyias, uas yog, ib qho chaw nres nkoj yog siv los ua kom tiav qhov xa thiab txais, yog li nws yog hu ua ib qho fiber ntau.Cov optical transceivers TX thiab RX sawv cev tau txais thiab xa tawm.Muaj ob hom optical transceivers: ib qho yog ib hom thiab lwm hom yog dual-hom.Ib yam li txoj kev uas tsuas muaj ib txoj kab xwb, kev tsheb yuav raug congested.Yog hais tias nws yog ib tug dual-kab kab, nws yuav smoother ntau, yog li nws yog pom tseeb hais tias dual-hom transceivers yog ruaj khov zoo dua.
Tib fiber ntau txhais tau hais tias tsuas yog ib qho fiber ntau siv los txuas ob lub transceivers.Dual fiber ntau ntau thiab xav tau ob fibers, thiab tus nqi ntawm ib fiber ntau dua me ntsis.Lub multi-mode transceiver tau txais ntau hom kev sib kis, qhov sib kis ntawm qhov deb kuj luv, thiab ib hom transceiver tsuas tau txais ib hom nkaus xwb;qhov kis tau tus mob yog qhov ntev.Txawm hais tias ntau hom tau raug tshem tawm, tseem muaj ntau daim ntawv thov hauv kev saib xyuas thiab kev sib kis luv luv vim tias tus nqi qis dua.Multi-mode transceivers sib haum mus rau ntau hom optical fibers, thiab ib hom thiab ib hom sib txuas mus rau ib leeg.Lawv tsis tuaj yeem sib xyaw.
